How Bhutan scored
We evaluated eSIM options for Bhutan using provider plan data and TashiCell's network specifications. 2 carrier networks accept eSIM roaming connections in Bhutan: TashiCell and B-Mobile. 6 plans from 5 providers form the basis of our comparison. Pricing starts at $3.12/GB on 4G LTE.
Two carriers operate in Bhutan: TashiCell and B-Mobile. TashiCell publishes the wider footprint, and B-Mobile is the fallback where the primary map thins.
The pricing ladder spans from 1GB at $4.99 ($4.99/GB) to 20GB at $62.31 ($3.12/GB). Best per-GB value sits at 20GB for $62.31 ($3.12/GB), our recommended tier for most Bhutan travelers. Holafly adds an unlimited daily option from $2.99/day, which suits heavy data users on trips of 5+ days. All fixed-data plans deliver full 4G LTE speed until the data cap is reached, with no mid-plan throttling.
Network coverage in Bhutan concentrates around urban centers and major transport routes. TashiCell provides the most consistent signal for travel eSIM users.
HelloRoam scores 9.5/10 for Bhutan, the highest among 5 ranked providers. Airalo trails at 9.3/10. These scores reflect Bhutan-specific conditions: TashiCell routing, 6 available plans, and 4G LTE as the network standard. Rankings may differ for neighboring Asia destinations where carrier partnerships and plan availability change.
What the rubric scores
The rubric ranked 6 eSIM plans from 5 providers for Bhutan on five dimensions: Coverage (25%), Pricing (25%), Network tier (20%), App features (15%), Support access (15%). Each provider takes a 1-5 mark per dimension, and the weighted total is doubled to give the /10 display score.
Where the inputs come from
Scores for Bhutan use the published weighted formula: Coverage (25%), Pricing (25%), Network tier (20%), App features (15%), and Support access (15%). Each dimension receives a raw score from 1 to 5. The composite multiplies by 2 for a 0-10 display scale. Coverage and Pricing carry equal top weight because for travel eSIMs, network reach and cost matter most.
Country-specific adjustments for Bhutan: Single-carrier markets like Bhutan receive a ceiling of 4.0/5 on Coverage, since no failover redundancy exists. Unlimited plan availability in Bhutan adjusts the Pricing dimension to weight per-day unlimited rates alongside per-GB fixed rates. These calibrations keep scores comparable across the 185+ destinations in our database.
The scoring spread across 5 providers for Bhutan is 1.5 points (HelloRoam at 9.5/10 down to Nomad at 8.0/10). A spread under 1.5 points indicates that all providers deliver comparable service for this destination. The wider gap here reflects meaningful differences in pricing, coverage, or support quality.

Bhutan Network Landscape
Bhutan has 1 mobile network: TashiCell (4G). TashiCell delivers the strongest coverage combination. All 5 providers route through these carriers.
Carrier Partnerships
Bhutan operates 1 mobile network: TashiCell (4G). TashiCell serves as the primary routing partner for travel eSIMs in this market. All five ranked providers route exclusively through TashiCell. Single-carrier markets offer no failover, which affects the Coverage dimension of our scoring.
TashiCell publishes 4G LTE across Bhutan, and every ranked provider attaches to it rather than to a network of its own. Single-carrier coverage means no automatic failover. Coverage quality depends entirely on TashiCell's tower infrastructure and geographic reach in Bhutan.
Carrier selection in Bhutan is largely predetermined by TashiCell's dominant roaming agreements. Providers compete on plan structure, pricing, and service quality rather than network access. Coverage scores follow the published partner list rather than anything measured on the ground.
